Isla ; Luis C. Cortizo ABSTRACT The coasts of southern Buenos Aires, Patagonia and Tierra del Fuego are dominated by cliff erosion. Mean rates of cliff retreat are estimated to be about 0.5-0.6 m/year by comparing old photographs with modern satellite images. Considering the height of the Patagonian and Fueguian cliffs (70 to 120 m), the volume of sediment eroded from these cliffs exceeded the volumes provided by the erosion of the cliffs of Buenos Aires (10 to 20 m height). These erosion rates support an estimated delivery of 217 million tons of sediment per year to the continental shelf, exceeding significantly the 22 millions of tons/year transported by the larger Patagonian rivers Negro and Colorado. -
First Record of an Extinct Marabou Stork in the Neogene of South America
First record of an extinct marabou stork in the Neogene of South America JORGE IGNACIO NORIEGA and GERARDO CLADERA Noriega, J.I. and Cladera, G. 2008. First record of an extinct marabou stork in the Neogene of South America. Acta Palaeontologica Polonica 53 (4): 593–600. We describe a new large species of marabou stork, Leptoptilus patagonicus (Ciconiiformes, Ciconiidae, Leptoptilini), from the late Miocene Puerto Madryn Formation, Chubut Province, Argentina. The specimen consists mainly of wing and leg bones, pelvis, sternum, cervical vertebrae, and a few fragments of the skull. We provisionally adopt the traditional system− atic scheme of ciconiid tribes. The specimen is referred to the Leptoptilini on the basis of similarities in morphology and intramembral proportions with the extant genera Ephippiorhynchus, Jabiru,andLeptoptilos. The fossil specimen resembles in overall morphology and size the species of Leptoptilos, but also exhibits several exclusive characters of the sternum, hu− merus, carpometacarpus, tibiotarsus, and pelvis. Additionally, its wing proportions differ from those of any living taxon, providing support to erect a new species. This is the first record of the tribe Leptoptilini in the Tertiary of South America. Key words: Ciconiidae, Leptoptilos, Miocene, Argentina, South America. Jorge I.

Upper Paraná Atlantic Forest Program
Upper Paraná Atlantic Forest Program The Upper Paraná Atlantic Forest – locally called Selva Misionera or Paranaense - is one of the world’s most biodiverse subtropical ecoregions. Spread across three countries – Argentina, Brazil and Paraguay – these forests are one of the planet’s most threatened areas as a result of past and present deforestation. Over the last decade, Fundación Vida Silvestre Argentina (FVSA), WWF’s associate organization, has been working towards the conservation of the forests of the Misiones Province. These forests –located in northeastern Argentina- are one of the largest forest blocks that still remains, and one of the few that still houses a jaguar population. From the heart of the jungle, FVSA-WWF’s office in Puerto Iguazú, just a few kilometers away from the impressive scenario offered by the Iguazú Falls, promotes conservation and sustainable development actions. Some of these undertakings are the Misiones Green Corridor and the Biodiversity Vision, a planning tool for the ecoregion. The Upper Paraná Atlantic Forest (UPAF) covers The Misiones Green Corridor was singled out in most part of the Misiones Province in northeastern the Biodiversity Vision as the most important area Argentina, and expands through the south of where to focus local actions with regional impact.

Due to its Within this framework, FVSA-WWF continues importance, it was included in the WWF “Global pressuring for the complete implementation of the 200” list as one of the most endangered ecoregions Green Corridor Law, which created a 1,1 million in the world. hectare Integral Conservation and Sustainable Development Area. -
Lithium Extraction in Argentina: a Case Study on the Social and Environmental Impacts
Lithium extraction in Argentina: a case study on the social and environmental impacts Pía Marchegiani, Jasmin Höglund Hellgren and Leandro Gómez. Executive summary The global demand for lithium has grown significantly over recent years and is expected to grow further due to its use in batteries for different products. Lithium is used in smaller electronic devices such as mobile phones and laptops but also for larger batteries found in electric vehicles and mobility vehicles. This growing demand has generated a series of policy responses in different countries in the southern cone triangle (Argentina, Bolivia and Chile), which together hold around 80 per cent of the world’s lithium salt brine reserves in their salt flats in the Puna area. Although Argentina has been extracting lithium since 1997, for a long time there was only one lithium-producing project in the country. In recent years, Argentina has experienced increased interest in lithium mining activities. In 2016, it was the most dynamic lithium producing country in the world, increasing production from 11 per cent to 16 per cent of the global market (Telam, 2017). There are now around 46 different projects of lithium extraction at different stages. However, little consideration has been given to the local impacts of lithium extraction considering human rights and the social and environmental sustainability of the projects. With this in mind, the current study seeks to contribute to an increased understanding of the potential and actual impacts of lithium extraction on local communities, providing insights from local perspectives to be considered in the wider discussion of sustainability, green technology and climate change. -

Earlier indices developed for Argentina (Velázquez, 2008; 2010a) provided basically two dimensions: a) socio-economic and b) environmental. Socio-economic dimension embraces such indicators as education, health and housing, while environmental one considers three aspects: nature-based recreational resources, socially constructed recreational resources and environmental problems. -

The eight species involved are the following: European hare (Lepus europaeus), European rabbit (Oryctolagus cuniculus), wild boar (Sus scrofa), and red deer (Cervus elaphus) were all introduced from Europe (Austria, France, Germany, and Spain) to either or both Chilean and Argentine Patagonia. American beaver (Castor canadensis) and muskrat (Ondatra zibethicus) were introduced from Canada to Argentine Tierra del Fuego Island (shared with Chile). The American mink (Mustela vison) apparently was brought from the United States of America to both Chilean and Argentine Patagonia, independently. The native grey fox (Pseudalopex griseus) was introduced from Chilean to Argentine Tierra del Fuego. -
